Soil acidity meter is used to detect soil pH instrument, can be directly inserted into the soil to measure the pH of the soil, compared with the traditional measurement of soil pH method is different, the operation is simpler, directly inserted into the soil measurement can better reflect the actual situation
of the soil.
A soil acidity meter is composed
of a combination of an ammeter, a metal sensor, and a functional value switching device that indicates the values.
That is, a hardware system with a metal sensor as the core, which is in contact with the soil by the metal sensor and uses the redox reaction in the chemical reaction, the resulting current
.
The magnitude of the current value drives the cell data of different pH and humidity values corresponding to the ammeter (without the support of batteries or other external power sources
).
Advantage 1.
Directly inserted into the soil measurement can better reflect the actual situation of the soil 2.
Metal probe, not as delicate as glass 3.
No need to replace the probe, normal service life of more than 3 years 4.
No battery, do not worry about no electricity 5.
Daily use, simple
maintenance.
